Claims. (Cl. 155-447) Our invention relates to a new and useful improvement in a folding high chair.

It is an object of the present invention to provide a folding high chair which will be simple in structure, economical in manufacture, durable, easily and quickly moved from folded to unfolded position and vice versa and which will be stable and rigid when moved to unfolded or normal position for use.

Other objects will appear hereinafter.

It is recognized that various modifications and changes may be made in the detail of structure illustrated without departing from the invention and it is intended that the present disclosure shall be considered to be but the preferred embodiment.

Forming a part of this application are drawings in which, i

Fig. 10 a fragmentary view similar to Fig. 3 with parts removed.

Fig. 11 is an elevational view showing the invention in fully folded position.

As shown in the drawings, the invention comprises a pair of legs 7 and 8 which are extended across each other and located at one side of the chair. A similar pair of legs 9 and 10 are extended across each other and located at the other side of the chair, these legs being, at their line of crossing, pivotally connected together by the connecting rod 11. A brace bar 12 serves to connect the legs 8 and 10 and a similar brace bar 13 serves to conmeet the legs 7 and 9. The legs 8 and 10 may be considered to be the rear legs and the legs 7 and 9 may be considered to be the front legs. The upper ends of the rear legs 8 and 10 are pivotally connected to a lug "15 which is secured to and projects downwardly from the seat 14, the pivotal connection being made by the pivot pin 15-a. Pivoted at one end to this same pivot pin 15-a is a brace bar 16 the upper end of which is pivotally connected to a lug 17 of a U-shaped structure embodying the big'ht 18. This U-shaped member may be considered a supporting frame as it supports the tray 24 which is detachedly mounted thereon. Mounted on the back 27 is an angle plate having the sides 20 and 20-a, the side 20-a having lugs 20-b through which securing means may be projected to secure this plate in fixed relation to the back 27. The lower end of the plate 20 is pivotally connected to a bracket lug 22 which is fixedly mounted on the seat 14. An outwardly bent lug 21 lies in the same plan as the plate 20 and the back 27 is pivoted by means of this lug 21 to the arms 17 of the supporting frame.

Projecting outwardly from the lug 22 is an angularly turned flange 23 which serves as an abutment and which, when the chair isin fully unfolded position, engages the "ice front legs 9 and 7 adjacent their upper ends so as to limit further swinging movement of the various parts. When the chair is in the position shown in Fig. 1, weight placed upon the seat 14 would have a tendency to swing the legs farther apart at their upper ends. This is prevented, however, because of the abutment 2'3 engaging the legs 7 and 9. Consequently, the chair cannot swing into folded position once it has been fully unfolded and weight is placed upon the seat 14.

When it is desired to fold the chair into the folded position a forward pressure on the upper edge of the back 27 will cause the back to rock on its pivotal connection with the upper ends of the legs 7 and 9. At the same time the supporting frame will be carried forward for a slight distance without changing its plane. In this movement, the arm-s 16 will rock forwardly at their upper ends swinging on their lower pivoted ends. The subsequent movement will cause the rear legs 8 and 10 to move at their lower ends int-o approach to the lower ends of the front legs 7 and 9. The supporting frame will then rock on its pivotal connection with the back 27 while at the same time the bottom will rock upwardly on the pivot pin 15a. The movement to folded or unfolded position centers around the pivot pin 32 which pivotally connects the upper ends of the legs 7 and 9 to the lug 28. When in fully folded position, the front and rear legs are substantially in contact and a very compact structure is provided. In order to unfold the chair, it is but necessary, while the structure is resting on the lower ends of the front legs to swing the upper edge of the back 27 upwardly and the various parts will reverse their swinging movement.

In the drawings, I have illustrated a swingable part 25 which is mounted on the seat 14 and projects downwardly therefrom and which carries a swingable foot rest 26, the portion 25 engaging against a stop 37. As shown in Fig. 9, the swingable member 25 is provided with a knuckle 62 tlo receive a pintle 63 mounted under surface on the seat What we claim is:
